Make sure the tower has cleared the truck body, cab, and lights before
rotating. The recommended procedure for tower operation is a slow,
steady movement of the control lever. This will produce a smooth tower
operation.
Rapid movement of the control levers will result in rough jerking of the
tower. This will create excessive loading on the tower structure. This kind
of operation is unsafe and will lead to premature wear and possible
structure failure.
The tower can be elevated from minus 4 degrees to plus 75 degrees from horizontal while in
any position that does not cause an interference with the body or cab.
EXTEND AND RETRACT
Extend the tower by pushing the left control lever, located at the control box, inward.
Retract the tower by pulling the left control lever, located at the control box, outward.
ROTATION
Rotate the tower to the left by pushing the center control lever, located at the control box,
inward.
Rotate the tower to the right by pulling the center control lever, located at the control box,
outward.
The tower can rotate a continuous 360 degrees either to the left or to the right.
